Brazil's Minister of Health, Alexandre Padilha, urged citizens traveling to the 2026 World Cup to be vaccinated against measles due to outbreaks in North America.
The warning comes as the tournament will be hosted across three countries: the U.S., Canada, and Mexico [1]. Health officials are concerned that the high volume of international travel could lead to the reintroduction and spread of the virus within Brazil [2], [3].
Padilha issued these guidelines in April 2026 during the preparations for the event. He noted that active transmissions of the disease are occurring in the U.S., Canada, and Mexico [1]. "Who is going to the Cup must be vaccinated," Padilha said [1].
Reports on the scale of the outbreak in the U.S. vary. Some data indicates there have been more than 1,700 cases [1], while other reports cite 222 cases [4]. Despite the discrepancy in numbers, the health ministry maintains that the risk to Brazilian citizens is significant.
"The measles outbreak in the US represents a risk for Brazil," Padilha said [4]. The ministry is emphasizing the urgency of vaccination now to ensure travelers are protected before the start of the tournament.
Measles is a highly contagious viral disease that can be prevented through vaccination. By targeting travelers, the Brazilian government aims to create a buffer against the potential import of the virus during the global sporting event.
“"Who is going to the Cup must be vaccinated."”
The Brazilian government is treating the 2026 World Cup as a potential public health vulnerability. Because measles is extremely contagious, the mass movement of people between North America and South America creates a corridor for the virus. This proactive vaccination drive is an attempt to prevent a localized outbreak in the host nations from becoming a national health crisis in Brazil.
